First, the raw material processing stage
1. Substrate pretreatment technology
◦ Polyester film (PET) or polyimide (PI) substrates need to be treated with a corona or applied with a sublayer to improve the adhesion of the subsequent carbon layer.
◦ Breaking point: Nanoscale coating technology (e.g., sol-gel method) can improve substrate surface uniformity and reduce edge burrs during slitting.
2. Carbon layer formulation and coating
◦ The rheological properties of wax-based/resin-based/mixed-based carbon pastes directly affect the slitting quality, and parameters such as viscosity and solid content need to be controlled.
◦ Process breakthrough: High-precision slot die coating technology to achieve a thickness error of ± 1μm and reduce thickness fluctuations during slitting.
Second, the core technology and structure of the slitting machine
1. High-precision slitting knife system
◦ Round knife slitting technology: using cemented carbide or diamond coated blades, the blade angle is accurate to 0.1°, and the service life is increased by 3 times.
◦ Laser slitting (emerging technology): non-contact cutting for ultra-thin ribbons (< 3 μm), there is no thermal damage at the edges, but the equipment cost is high.
◦ Breaking point: Adaptive tool wear compensation system that automatically adjusts pressure by monitoring the blade status in real time.
2. Tension control technology
◦ Multi-stage closed-loop tension control (unwinding→ traction → winding), using magnetic particle brake + servo motor + tension sensor linkage, fluctuation range < 0.5N。
◦ Innovative solution: AI-based predictive tension adjustment to predict the elastic deformation trend of materials in advance.
3. Web Guiding System (EPC)
◦ Infrared or CCD sensor detects the edge position and dynamically adjusts the guide roller with an accuracy of ± 0.1mm.
◦ Breakthrough: Machine learning algorithm optimizes the correction response speed and adapts to high-speed slitting (>300m/min).
4. Dust removal and static elimination
◦ The combination of ionic air bar + vacuum adsorption device prevents the accumulation of toner powder from affecting the slitting accuracy.
◦ New technology: low-temperature plasma dust removal, the efficiency is increased by 40%.
Third, process difficulties and breakthroughs
1. Ultra-narrow web slitting (< 1mm）
◦ Challenge: Blade vibration causes a serpentine transport.
◦ Solution: Air bearing support knife shaft, radial runout < 0.005mm。
2. Dust-free slitting environment
◦ Class 1000 design, with local laminar flow hood, to reduce particle pollution.
3. Winding uniformity control
◦ Constant linear speed + variable torque winding, with inflatable shaft precision clamping, end face uniformity < 0.2mm。
Fourth, intelligent and automated upgrading
1. Digital twin technology
◦ Virtual debugging of slitting parameters (such as tension and speed) to reduce the loss of physical test machine.
2. Visual quality inspection system
◦ On-line detection of slitting edge defects (such as burrs, serrations), and automatic sorting of defective products.
3. Energy optimization
◦ The regenerative braking system recovers the energy during slitting and deceleration, reducing energy consumption by 15%.
Fifth, the future direction of technology
• Flexible electronic grade slitting: adapt to the needs of ultra-thin ribbons for wearable devices.
• Quantum dot coating slitting: for the high-resolution color thermal transfer market.
• Modular design: Quickly switch between plug-and-play cutter sets with different widths (e.g. 1mm→10mm).
summary
The technical competition of ribbon slitting machine has shifted from pure mechanical accuracy to "material-equipment-algorithm" collaborative innovation. Future breakthroughs will focus on: (1) nanoscale surface treatment technology; (2) ultra-high-speed dynamic control algorithm; (3) Low-carbon manufacturing process. Companies need to establish technical barriers on core components (e.g., high-rigidity frames, intelligent tool magazines) and process databases (e.g., material-parameter matching models).
